Lady fern · Athyrium filix-femina

Why is my Lady fern dropping its fronds?

It is less common for this plant to drop fronds, which usually happens due to extreme environmental stress like sudden temperature changes or low humidity. Check the air around your plant for drafts or dry heat sources first.

Check these first

  1. Check if the plant is near a heater or air conditioning vent.
  2. Measure the humidity levels in the room.
  3. Inspect the fronds for signs of extreme dryness.

Likely causes

  1. Dry air

    Most likely

    How to tell: The fronds become brittle, turn brown at the edges, and then fall off. This often happens in winter when indoor heating dries out the air.

    What to do: Place the fern on a pebble tray filled with water to increase local humidity. You can also mist the fronds daily or move the plant to a bathroom with a window.

  2. Temperature shock

    Possible

    How to tell: The fronds wilt and drop suddenly after being placed near a drafty window or a heater. The plant looks healthy one day and collapses the next.

    What to do: Move the fern to a stable location away from air vents, radiators, or drafty doors. Keep the room temperature between 60 and 75 degrees Fahrenheit.

When to worry

If the entire plant loses its fronds rapidly, it is in severe distress. It is normal for the plant to go dormant and lose fronds in late autumn as winter approaches.

Stopping it coming back

Keep your fern away from direct airflow and maintain consistent moisture in the soil.
